If you really want to maximize the effectiveness of your silenced firearm, you need to use subsonic ammo. The downside is that many times the rounds don't have enough gas pressure to properly operate the firearm. Engel Ballistic Research makes subsonic 7.62x39 ammo that when paired with a silencer like the DeadAir Wolverine actually cycle the rifles action. We take a look at two different flavors of the Engel Ballistic Research subsonic 7.62x39 ammo and fire them over the sound meter.
